Where are set the ${VARIABLE} variables ? #22

Open JBPressac opened 2 years ago

JBPressac commented 2 years ago

Hello,

I noticed that https://github.com/RMLio/social-media-archiving/blob/b0d0cd31ad12d935ed474f9544e04c4a0691c103/mappings/collection-harvest-seeds.yml for instance uses variables as ${SFM_DB_HOST}, ${SFM_DB_PORT} or ${SFM_DB_DATABASE} but where does those variables come from ? Where are they set ?

I am using RMLmapper. Does this kind of variables would work with this application ?

Thanks,

Hi @JBPressac

They are used by the Social Feed Manager. They are explained at https://sfm.readthedocs.io/en/stable/install.html When you generate RML rules from the YARRRML rules, you need to provide them to the YARRRML Parser using -e parameter.

Hi @JBPressac

indeed, as @pheyvaer said they are used by the Social Feed Manager. However, I am not 100% sure that passing the variables with -e will work with the mapping files in this repository out of the box, because I used the curly braces notation => ${..}.

I did this because I have assigned values to these variables in a .env file and used a fork of yarrrml which automatically loads the variables from a found .env file.

Thus for the -e solution proposed by Pieter used by the most up-to-date yarrrml-parser, you may have to adapt the syntax of the variable within the yarrrml file, for example $(_SFM_DB_HOST) (see the documentation linked by @pheyvaer ).

Hello,

Thank you for your answers. However, @SvenLieber, the -e parameter does not work with references set in the variables part of a .yml file (with the YARRRRM Parser version 1.3.4).

For instance, yarrrml-parser -i rules-prelib.yml -o rules-prelib.rml.ttl -e username=John applied to:

Hi,

sorry for my late answer.

Yes, this is right! The variables part I use is custom.

You may have to use the $(_...) variables directly in the mapping. I might be wrong, but it could even be that these variables are only read within the subject or predicate-object parts of mappings. If this is true, I suggest to open an issue in the repository of the yarrrml-parser to request the feature that external variables can also be used, for example, in the sources block.
